[POWERPC] Fix IO space on PCI buses created from of_platform

2007-05-17T11:11:14+00:00

This changes the way of_platform_pci creates PCI host bridges such
that it uses request_phb_iospace() for mapping the IO ports, instead
of using the dynamic hotplug stuff.  That guarantees the IO space
stays within the 2GB limit and thus doesn't break half of the legacy
drivers around.

Fixes a couple of warnings due to missing IO space while at it.

This patch is a temporary workaround for 2.6.22 before a more complete
rewrite of IO mappings is merged in 2.6.23

[POWERPC] Early serial debug support for PPC44x

2007-05-08T04:47:33+00:00

This adds support for early serial debugging via the built in
port on IBM/AMCC PowerPC 44x CPUs.  It uses a bolted TLB entry in
address space 1 for the UART's mapping, allowing robust debugging both
before and after the initialization of the MMU.

[POWERPC] Add uevent handler for of_platform_bus

2007-04-12T17:55:13+00:00

Adding this handler allow userspace to properly handle the module
autoloading. The generation of the uevent itself is now common to
all bus using of_device, so not much code here.

[POWERPC] powerpc: Workaround for of_platform without "reg" nor "dcr-reg"

2006-12-04T09:40:17+00:00

Devices with no "reg" nor "dcr-reg" property are given a bus_id which
is the node name alone. This means that if more than one such device
with the same names are present in the system, sysfs will have
collisions when creating the symlinks and will fail registering the
devices.

This works around that problem by assigning successive numbers to such
devices.

[POWERPC] Generic OF platform driver for PCI host bridges.

2006-12-04T09:38:49+00:00

When enabled in Kconfig, it will pick up any of_platform_device
matching it's match list (currently type "pci", "pcix", "pcie",
or "ht" and setup a PHB for it.

Platform must provide a ppc_md.pci_setup_phb() for it to work
(for doing the necessary initialisations specific to a given PHB
like setting up the config space ops).

It's currently only available on 64 bits as the 32 bits PCI code
can't quite cope with it in it's current form. I will fix that
later.
